This study involves the development and preliminarily testing of In-Home Cognitive Behavioral Therapy (IH-CBT), a psychological treatment grounded in the cognitive model but adapted for administration in conjunction with home visitation. IH-CBT is designed to (1) use the techniques and approaches of CBT which have received strong empirical support, (2) be implemented in the home setting, (3) meet the needs of young postpartum mothers in their first year of home visitation, and (4) be seamlessly integrated with home visitation to maximize the likelihood of recovery from depression, prevent relapse, and increase of the benefits of home visitation. IH-CBT will be delivered by trained therapist who will provide 15 treatment sessions followed by a 1 month booster session. A small-scale randomized clinical trial will be conducted contrasting IH-CBT delivered in conjunction with home visitation and home visitation alone ("typical home visitation"—THV). Mothers in the THV condition will be able to obtain treatment in the community if they choose.
